# Greylisting in cPanel

> Greylisting is on by default to block spam, but it can delay the first email from a new sender. Here's how it works and how to turn it off for a domain.

Greylisting is turned **on** for all Ruachost email accounts. It blocks a large share of spam before it reaches your inbox.

## How it works

The first time an unknown server sends email to your domain, our server politely asks it to try again a few minutes later. Real mail servers retry automatically, and the message is delivered. Most spam tools never retry, so their messages never arrive.

After a sender has passed this check once, their future emails arrive straight away.

## What you might notice

- The **first** email from a new sender can arrive a few minutes late, occasionally longer if the sending server waits a while before retrying.
- One-time codes, sign-up confirmations and password-reset emails from a service you haven't heard from before may take longer than usual.

This is normal and the email isn't lost. If a message from a new sender seems to be missing, wait 15–30 minutes before asking them to resend it.

## Turn greylisting off for a domain

If delays cause problems, for example when you rely on fast verification codes, you can turn greylisting off for any of your domains:

1. Log in to cPanel.
2. Under **Email**, open **Greylisting**.
3. Find your domain and switch its toggle **off**.

Changes take effect immediately. You can switch it back on at any time.

> **Caution:**
With greylisting off, you're likely to receive more spam. Make sure [spam filters](https://helpcenter.ruachost.com/email/cpanel-email/filtering-unwanted-e-mail-spam-in-cpanel/) are turned on for your account.
